Dead of Winter

Dead of Winter: A Crossroads Game is a post-apocalyptic semi-co-operative board game set in the aftermath of zombies taking over the world. 

Barriers

Self-made barriers that fit perfectly in the barrier slots on the board. My employer's office has a beverage machine and there are disposable wooden sticks to stir your hot coffee as plastic spoons are no longer an environmentally acceptable solution. I took some of them back home and made a bunch of barriers. Simple and effective. I need more, of course, another batch is waiting to be finished.

Oh and these are directly usable in the Cthulhu: Death May Die boargame as well when playing with the investigator character "Michelle".
